Greyline DFM 6.1 Doppler Flow Meter
Measures, Displays, Totalizes and Controls from Outside a Pipe
Greyline Doppler Flow Meters monitor the flow rate of dirty or aerated liquids including: wastewater, sewage, slurries, abrasives, and viscous liquids. Recommended for full pipes and any fluid that contains solids or bubbles.
The clamp-on sensor is mounted on the outside of any DFM 6.1 pipe ½ inch / 12.7mm diameter or larger. To measure velocity an acoustic signal is reflected back to the sensor from moving particles or gas bubbles suspended in the fluid. Flow is calculated based on configured pipe ID.
Installation is easy - without shutting down the flow system. No contact is made with the moving fluid and no pipe cutting or drilling is required. There is no fouling or scale build-up on the sensor.
The Doppler Flow Meter includes an ultrasonic sensor, an DFM 6.1 easy to use 5-key calibration system, a large digital flow rate display with totalizer, isolated 4-20mA output, 26 million point data logger, and two programmable control relays. The sensor is classified as non-incendive and an intrinsically safe sensor is optional.
